I have a problem with a PSB file that cannot be opened because I get an end-of-file error. Tried updating the program, tried using repair programs but they all only work for PSD files. I tried to recover a project from an overwritten file. Reset preferences didn't work either. I'm in a bind right now because I want this file to work back and none of the solutions will work. I even wrote to @AdobeCare on Twitter, and despite their help, I still haven't recovered the file.
